Optos Widefield Retinal Imaging
The Optos Daytona uses two lasers to scan the retina and the underlying choroid through a range of 200°. By comparison, standard digital retinal photography captures only the central 45° of the retina. Normally to see such peripheral regions of the retina it would be necessary to dilate your pupils, but in the vast majority of cases the Optos is able to take images without the need for dilation.
Using the Optos to view the peripheral retina is particularly important for higher degrees of myopia (short-sightedness), where there is a greater likelihood of peripheral retinal degenerations, holes and tears. It is also important for diabetics, as sometimes diabetic retinal disease is not visible centrally but only in the periphery. If you have symptoms such as flashes or floaters, widefield imaging is especially useful for detecting retinal holes, tears and detachments.
We also usually perform Optos widefield retinal imaging on patients' first visit to the practice. This is done especially to detect any pigmented retinal lesions that require ongoing monitoring for change, in much the way that pigmented abnormalities of the skin might be followed.
The fee for Optos widefield retinal imaging is $52 and does not attract a Medicare rebate.
